Inversion symmetry breaking in the probability density by surface-bulk hybridization in topological insulators
Jorge David Castaño-Yepes, Enrique Muñoz
We analyze the probability density distribution in a topological insulator slab of finite thickness, where the bulk and surface states are allowed to hybridize. By using an effecti…
Electromagnetic coupling and transport in a topological insulator-graphene hetero-structure
Daniel A. Bonilla, Jorge David Castaño-Yepes, A. Martín-Ruiz +1
The electromagnetic coupling between hetero-structures made of different materials is of great interest, both from the perspective of discovering new phenomena, as well as for its…
Optical conductivity as a probe of the interaction-driven metal in rhombohedral trilayer graphene
Vladimir Juričić, Enrique Muñoz, Rodrigo Soto-Garrido
Study of the strongly correlated states in van der Waals heterostructures is one of the central topics in modern condensed matter physics. Among these, the rhombohedral trilayer gr…
Electronic transport in Weyl semimetals with a uniform concentration of torsional dislocations
Daniel A. Bonilla, Enrique Muñoz
In this article, we consider a theoretical model for a type I Weyl semimetal, under the presence of a diluted uniform concentration of torsional dislocations. By a mathematical ana…
The role of morphology on the emergence of topologically trivial surface states and selection rules in topological-insulator nano-particles
Jorge David Castaño-Yepes, Enrique Muñoz
Confined electronic states and optical transitions in 3D topological insulator nanoparticles have been studied in the literature, assuming idealized geometries such as spheres or i…
Thermo-magneto-electric transport through a torsion dislocation in a type I Weyl Semimetal

We studied theoretically the effect of a low concentration of adsorbed polar molecules on the optical conductivity of graphene, within the Kubo linear response approximation. Our a…
Dislocation defect as a bulk probe of monopole charge of multi-Weyl semimetals
Rodrigo Soto-Garrido, Enrique Muñoz, Vladimir Juričić
Multi-Weyl semimetals feature band crossings with the dispersion that is, in general, linear in only one direction, and as a consequence their band structure is characterized by th…

Horacio Falomir, Enrique Muñoz, Marcelo Loewe +1
In this article, we investigate the temperature and chemical potential dependence of the optical conductivity of graphene, within a field theoretical representation in the continuu…
